SPECIFICATION forming part of Letters Patent No. 756,378, dated April 5, 1904.

Application filed July 2, 1903. Serial No. 164,042. (No model.) f

To (LI/, L11/1,071?, it muy concern:

Be it known that we, JOHANN J AKOB KOCH and JOSEPH HMBELI, citizens of the Republic of Switzerland, residing at lVohlen, Aargau, Switzerland, have invented new and useful Improvements in Cook-Stoves, of which the followingis a specification.

The present invention has reference to improvements in cook-stoves. and relates more especially to cook-stoves with burners for consuming gaseous or liquid fuel, as coal-gas, coal-oil, or the like; and the object of the invention is to provide a stove in which all of the generated heat is made use of to the best advantage.

With this object in view the invention consists of the construction and arrangement of parts as will hereinafter be described with reference to the accompanying drawings and specifically pointed out-in the appended claims.

In the drawings is shown by way of eX- ample a construction of stove with gas-burners, and it represents, in

Figure l, a sectional longitudinal elevation; Fig. 2, a plan View with top plate removed, and Fig. 3 a cross-sectional elevation.

The stove essentially consists of an oblong rectangular frame a, resting upon suitablyornamented feet. The upper edge of this frame 'a is formed by a T or flanged rail I), as shown in Figs. l and 3. Upon the horizontally-extending rib of this T-rail rests the water-receptacle c. A trifle below the bottom line of this receptacle are arranged the burners (Z, secured in a suitable manner in the frame a.

Above the burners and concentrically therewith are provided tubular chambers e in the water-receptacle c, adapted to receive the cooking vessels. The water-receptacle c is closed at the top by a removable cover-plate 'f, and concentric partly-overlapping rings g serve to more or less cover the receptacle c and chambers c, according to the diameter of the cooking vessel used.

A very desirable and 1important feature of our invention is in providing a large waterspace between the tubular chambers e, where a supply of hot water may be kept constantly on band and alsowhere avessel may be placed for the purpose of keeping the contents thereof warm until ready for use without further cooking or "drying up of the food. This we attain by providing in the top f of the water-receptacle an opening communicating with said water-space between the tubular chambers, which opening is capable of receiving a cooking vessel above mentioned. When not containing a vessel for the purpose above stated, the opening may be closed by a plate z, as shown in Fig. 1. The diameter of this opening may also be changed at y will by using the concentric rings g, above described. The hot water may be conveniently drawn oif at will by means of a faucet Q1, preferably situated in the side of the receptacle near the bottom between the tubular chambers, as shown in Figs. 2 and 3.

Below the burners are slidingly arranged in the frame a drip-pans c.

In the described stove the generated heatcooking vessel and not only heat the latter but also the water-receptacle walls. The pans 7c serve to receive overiiow from the cooking vessel or water-receptacle and other impurities and can easily be removed for emptying purposes. The water-receptacle is preferably made of cast-iron to prevent destruction in case the stove is put in operation without the water-receptacle having been previously filled.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is- 1. A cooking-stove, comprising a waterchamber provided with an open-ended passage for the reception of cooking utensils and with an opening in its top for the reception of like utensils to be heated by the water-bath or steam, and a support for said chamber; in combination with covers for said passage and opening and a fluid-fuel burner below the passage, for the purpose set forth;

2. A cooking-stove comprising a base open at top and bottom, a water-chamber supported by said base so as to form a continuation thereof and provided with an open-ended passage ing-gases collect in the chambers e around the for the reception of cooking utensils and with an opening in its top for the reception of like utensils to be heated by the water-bath or steam; in combination with covers for said for the reception of cooking utensils and with an opening in its top between said passages 'for the reception of a vessel to be heated by the water-bath or steam and a support for lsaid chamber; in combination with covers for said opening and passages and a Huid -fuel burner below each passage, for the purpose set forth. f

4. A cooking-stove comprising a base open at top and bottom, a water-chamber supported by said base and provided with open-ended upwardly-tapering passages for the reception of cooking utensils, with an opening in its top between said passages for the reception of a vessel to be heated by the water-bathor steam and with a draw-oif cock near its bottom; in combination with covers for said opening and passages and a fluid-fuel burner below .each of said passages, for the purposevset forth.

5. A cooking-stove comprising a base open at top and bottom, a water-chamber removably seated on said base and provided 'with openended passages for the reception of cooking utensils and with an opening in its top between said passages for the reception of a vessel to be heated by thewater-bath or steam; in cornbination with covers for said opening and passages and a fluid-fuel burner below each passage, for the purpose set forth.

6.l A cooking-stove comprising a base open at top and bottom, a water-chamber supported by said base and provided with open-ended passages for the receptionof cooking utensils and with an opening in its top between said passages for the reception of a vessel to be heated by the water-bath or steam; in combination with covers for said opening and passages, a fluid-fuel burner below each passage, and a removable drip-pan below each burner of substantially the same diameter as the wider end of said passages.

7. A cooking-stove comprising a base open at top and bottom, a seat encompassing the upper edge of said base, a liange encompassing said seat a water-chamber seating on-said seat and fitting into the iange thereof, said watercliamber provided with open-ended passages for the reception of ,cooking utensils and withv an opening in its top for the reception of like utensils to be heated by the water-bath or steam; in combination with covers for said passage and opening anda Huid-fuel burner below the passage, for the purpose set forth.

8,. In cook stoves, the combination of a frame, a anged upper edge on said frame, burners secured in said frame and drip-pans below said burners, a water-receptacle with tubular. chambers adapted to be removably fitted to said frame edge, a cover-plate on said water-receptacle, a smaller cover-plate in said cover-plate, a faucet in said water-receptacle, and a plurality of concentric, partly-overlapping rings to cover the said tubular chambers, all substantially as and for the purpose set forth.'

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
